Morgenglanz der Ewigkeit

"Morgenglanz der Ewigkeit" (Morning splendour of eternity) is a Christian hymn with German text originally by Christian Knorr von Rosenroth, written around 1690 and set to music for private devotion. It became known with a 1662 melody by Johann Rudolf Ahle. The song is part of modern German hymnals and songbooks. It was translated to English as "Come, Thou Bright and Morning Star", and as "Dayspring of Eternity".
